What Is Granule Loss on a Roof?

Your roof is crucial in protecting your home from the elements, including harsh weather conditions like rain, wind, and sunlight. Over time, however, your roof may start to show signs of wear and tear. One common issue that homeowners face is granule loss on their roof.

Granules are small, protective particles that are embedded in the surface of asphalt shingles. They provide a layer of defense against various elements, such as UV rays and precipitation. Granule loss occurs when these particles start to wear away, exposing the underlying asphalt material.

Causes of Granule Loss

There are several factors that can contribute to granule loss on a roof. Here are some of the most common causes:

1. Age: As your roof ages, it naturally becomes more susceptible to granule loss. Over time, the shingles may start to deteriorate, causing the granules to dislodge.

2. Weathering: Extreme weather conditions, such as heavy rain, hailstorms, and strong winds, can accelerate the granule loss process. These weather events can cause the granules to loosen and eventually wash away.

3. Poor Quality Shingles: If your roof was installed using low-quality shingles, they may be prone to granule loss. Inferior materials are more likely to deteriorate and shed their protective granules.

4. Improper Installation: If your roof was not installed correctly, it can lead to premature granule loss. Poor installation techniques can cause the shingles to become loose, leading to granule displacement.

5. Foot Traffic: Regular foot traffic on the roof, such as during maintenance or inspections, can cause the granules to dislodge. This is why it’s important to minimize unnecessary foot traffic on your roof.
